Organizational development involves improving organizational performance through organization-wide changes. There are different types of organizational structures such as traditional vs non-traditional, functional vs divisional, and centralized vs decentralized structures. Traditional structures have formally defined roles and resistance to change while non-traditional structures are flexible, adaptable, and have fewer employees. When organizations change, employees typically go through stages of denial, defense, discarding old ways, adaptation to new systems, and ultimately internalization of changes. Organizational culture comprises shared values and beliefs that establish workplace norms. Techniques for organizational change include management by objectives, survey feedback, and team building.
